gender sadness

Nikki. • 25 army vet ttc with husband
So I'm a little frustrated because at only 14 weeks I really want to know what my baby's gender is. Problem is my husband is in Iraq and comes home in June and wants me to wait till then to find out. 😩 ill be over 23 weeks. Am I being selfish?? I just feel like that's too close to a baby shower date and everything will be crammed.
